    Data Type Mismatch in QBASIC

    Hi Mikrom, Thanx for the tip. Code works for small numbers; I will now test for 10+ digit numbers. One more question: Is there a way of combining the 4 DIM statements into 1 line? eg DIM P1, P2, N1, N2 AS LONG Thanx pya

    Data Type Mismatch in QBASIC

    Hi Mikrom, Further to my post if I use PRINT instead of PRINT USING , the code works fine. But, PRINT USING should allow me to display the output number in detail instead of in scientific exp notation. Try the code with N = 3, 4, 5, 6, 59 and 288 to see how it works. Pervez

    Travelling Salesman Problem in QBasic

    Hi mikrom, I ran your code for 10 cities and it worked fine. But, I have a couple of questions and would be grateful if you could answer at your convenience. 1. I do not understand the first set of Distance Matrix - DATA 0,34,36 and the following 2 lines. 2. My 2nd question is where is the...

    Travelling Salesman Problem in QBasic

    Hi mikrom, When you have time can you please look at the ERROR I get when running your code. Also, I do not understand Lines 2320 - 2360. The Distance Matrix lines 2370 - 2384 I recognise as the distance between cities 1 to 7. But what do lines 2320 - 2360 represent? Regards Pervez PS: No...

    Travelling Salesman Problem in QBasic

    Has anyone written a code in QBasic to solve the Travelling Salesman Problem? I can solve it in Excel Solver but would be interested in the code. Pervezhttps://files.engineering.com/getfile.aspx?folder=855c4bc6-288a-40e1-b531-4633fbe519ff&file=TSP_-_SOLVER_v1.xlsx

    Error in Exponentiation

    Hi mikrom, A kindred spirit. Studied maths at uni but never enjoyed it. Too many exams and too much pressure. Now I enjoy it thoroughly (along with Physics). My main interests are in Prime Numbers and Cantor's Infinite Set theory. I also enjoy Linear Programming and use Excel's Solver to keep...
